West Nile Virus - County Larvicide Application
Last updated 5/25/2016 at 8:22am
The County of San Diego Vector Control Program (VCP) will conduct its second aerial mosquito larvicide application of the 2016 mosquito season at large waterbodies known to breed mosquitoes, throughout the county to Wednesday, June 1, 2016.
A helicopter will apply larvicide to reduce mosquito populations and reduce the risk of West Nile virus (WNV) transmission. The larvicide is made of naturally occurring bacteria which target mosquito larvae in the water and is not toxic to people, pets, fish or other insects.
VCP staff will be at the locations during the application to answer questions and monitor progress.
Additional larvicide applications will be conducted at three to four week intervals or as needed through the end of the mosquito season which is approximately October. Mosquito populations will continue to be monitored and tested for the presence of West Nile virus and other mosquito-borne diseases throughout the county.
